i'd strongly suggest using a project like crosstool:
it takes care of many many problems that people are likely to run into.
building things by hand nowadays is really only for people who want to
learn and fix things themselves.

i want to learn and maybe/if needed fix things myself - or understand better the details (longterm c/c++ developer with some linux background)

i've forgot to set linux arch correct - resulting in the wrong/missing headers - now im getting this error
